Residents in San Diego were treated to a surprise light show on Monday night.

Social media lit up in reaction to the bright, pulsing orb that streaked through the sky a little after 9 p.m.

The American Meteor Society log shows it received over 300 reports of a fireball, mostly in San Diego but stretching up the coast to Santa Barbara and inland to San Bernardino and Palm Desert. There were also several reports of a fireball sighting around Phoenix.

The National Weather Service told Fox 5 San Diego that it was possibly a meteor.
